Mukhtasar Bukhari

Narrated Ibn Umar (may Allah be pleased with them) that the Messenger of Allah (peace and blessings of Allah be upon him) looked into the well where the slain polytheists of Badr were lying dead and said: "Have you found true what your Lord promised you?" It was said to him: "Are you calling out to the dead?" So he (peace and blessings of Allah be upon him) said: "You do not hear better than they do, but they cannot respond."
